In the light of the Paris shooting incidents, France has chalked out a plan to bolster its counter-terrorism efforts.

Prime Minister Manuel Valls announced on Wednesday that the country will spend 425 million euros ($492 million) and create 2,680 anti-terror jobs as part of the plan.

The plan also envisages steps for better monitoring of the 'extremist threat.' PM Valls said that at present there are about 3,000 people across France who need to be kept under surveillance.

Valls also stated that the security forces would be provided with better equipment and protection, including bullet-proof vests. "We will pursue this fight against terrorism relentlessly," he said.

Earlier, France formally charged and detained four men accused of providing weapons to Amedy Coulibaly, one of the three gunmen involved in one of the deadliest terrorist attacks in the country.

A prosecutor gave details of four men charged with the attacks. The men reportedly supplied the weapons used by Amedy Coulibaly to kill a policewoman on 8 January. A day later, Coulibaly attacked a Jewish supermarket in Paris in which four hostages were killed.

On 7 January two brothers, Said and Cherif Kouachi, attacked the Paris offices of satirical magazine Charlie Hebdo, killing 12 people. All three gunmen were shot dead by police.

The full names of the men, the first to be charged in the Paris attacks, were not released.
